论文摘要
我们提出了一种新型技术，用于生成携带轨道角动量（OAM）的光束，从而增加模式纯度并减少通过数量级的奇异性分裂。该技术还可以控制和减轻比雷利长度小的传播距离内的光束差异。此外，我们分析了该技术的可调参数，该参数可以改变梁纯度与符合所需规范的功率的比率。仅使用相位调节的光学元件可以实现通过此技术的光束生成，从而降低了实验复杂性和梁的能量损失。
We present a novel technique for generating beams of light carrying orbital angular momentum (OAM) that increases mode purity and decreases singularity splitting by orders of magnitude. This technique also works to control and mitigate beam divergence within propagation distances less than the Rayleigh length. Additionally, we analyze a tunable parameter of this technique that can change the ratio of beam purity to power to fit desired specifications. Beam generation via this technique is achievable using only phase-modulating optical elements, which reduces experimental complexity and beam energy loss.
